摘要
通过在1个、2个和3个自由面状态的爆破振动试验,得出自由面个数的多少对爆破地震强度的影响规律。根据试验测试结果及分析,得出随着自由面数量的增加,爆破地震波强度的衰减系数α有变小的趋势,场地系数K大幅度减小,总体上爆破地震波强度降低很快。
According to blasting vibration experiments with one free face ,two free faces and three free faces ,the influence law of blasting vibration wave strength to quantity of free faces was set up. According to results of experiments and analysis ,it can be received blasting earthquake wave strength is attenuated faster with the increase of quantity of free face.
